GGF HQ with solar control film

GGF specifies solar control film to counteract excessive glare and heat gain

  • 17 May 2016

A high performance, neutral coloured external solar control film has been installed at the headquarters of the Glass and Glazing Federation to counteract the excessive glare from the sun. 

Despite the installation of high performance solar glass, occupants of the third floor office extension were still subject to an uncomfortably hot feeling when near a window. Although blinds could have been fitted to control the glare, they would have had little effect on the heat and also interrupted the panoramic views enjoyed from the building.

Solar glare

It takes 3 to 4 times more energy to reduce the temperature by 1 degree as it does to heat by 1 degree.

The external solar control film reduced the glare by 80% and heat by 70%. The film also reduces air conditioning usage by up to 30%, meaning it would save the company energy and costs in the long-term. A corresponding energy analysis showed that over 125 kWh of energy (£15) would be saved per square metre of glass.

Steve Rice, GGF Director of Technical Affairs, commented: “It is always pleasing to witness a first class example of how a window film installation can solve existing problems with glazing. This installation has vastly improved the working environment for the staff with a reduction in extreme glare coming through the windows from strong sunshine. 

Secondly applying window film has made the GGF Building more energy efficient, something that is always high on our agenda. The finished job looks superb and I am pleased a GGF Member company from the Window Film Group undertook the work.”

The window film offers an expected lifespan of over 10 years.
